"No use, Norman—get away—get away!" he cried hoarsely, frenziedly.

"Hackett—for God's sake—!" Norman half-leaped to the other, but an arm caught him, pulled him desperately onto the boat's surface. It was Sarja, the long craft flying over the roof beneath his control.

"They come!" he panted. "Too late now—" Frog-men were pouring up onto the roof from below. Sarja sent the craft rocketing upward, as Hackett gestured them away for a last frantic time before going down beneath the frog-men's onslaught.


he roof and the combat on it dropped back and beneath them like a stone as their craft ripped across the silvery dusk over the mighty frog-city. They were shooting toward the city's center, toward the green pool that was the entrance to the water-tunnel, while behind and beneath an increasing clamor of alarm spread swiftly. Norman raged futilely.

"Hackett—Hackett! We can't leave him—"

"Too late!" Sarja cried. "We cannot help him but only be captured again. We escape now and come back—come back—"

The truth of it pierced Norman's brain even in the wild moment. Hackett had fought and held back the frog-guards only that they might escape. He shouted suddenly.

"Sarja—the water-tunnel!" A half-dozen boats with frog-guards on them were rising round it in answer to the alarm!
